How do you download Blender 2.79
A release candidate can be downloaded at  https://builder.blender.org/download/



From the release Notes:


  As the 2.79 is an important release before the transition to the 2.8 series, please help Blender by testing the available builds and reporting possible issues.
  
  Compatibility Warning
  
  When using add-ons in Blender 2.79 that take advantage of the new data-block pointer properties, the resulting .blend files can't be opened in earlier versions of Blender. Attempting to open such .blend files in Blender 2.78c and earlier may crash.
